Hello everybody! I am new here and have not looked around much on the forum for an answer to my question, so sorry if this should be obvious to me but: I want to create a model of the Robert Boyle ever flowing flask for my class. For those of you who do not know what this is, it is basically a funnel with a hose that goes from the bottom, around, and back into the top of the funnel to replenish the supply... hence... ever flowing. Of all the videos on Youtube i have never seen one work well but i have recently come up with an idea. What if you put your mouth on the end of the hose and suck the water/soda/beer through until it reaches the end and flows into the funnel??? Would this be a type of venturi and would it work? I am planning on tying this but would like an answer is someone has one. Thanks for any suggestions or information you guys can give me!!!
